Abstract
This is the first demonstration of interhemispheric inhibition (IHI) during a locomotor output, arm cycling. IHI was quantified by assessing the depth of the ipsilateral silent period (iSP) evoked via transcranial magnetic stimulation of the motor cortex. There was a significant reduction in electromyography (EMG) amplitude of the iSP during cycling compared with the control EMG (16.8% ± 17.1%; p < 0.001). Depth and area for measuring the iSP during arm cycling are discussed. Novelty: This is the first study to demonstrate activation of the cortical circuit, interhemispheric inhibition, during a locomotor output.Keywords: central pattern generator; cortex moteur; exercice; exercise; générateur de schéma central; inhibition transcallosale; ipsilateral silent period; locomotion; motor cortex; période silencieuse ipsilatérale; transcallosal inhibition
